MILANES OJEA, María Rosario et al. Influence of nutritional status on birth weight in the third trimester. Rev Cubana Obstet Ginecol [online]. 2013, vol.39, n.3, pp. 226-235. ISSN 0138-600X.

Introduction: maternal nutritional status is a factor in fetal growth and weight of the newborn. There is scientific evidence that inadequate nutritional status and anemia in pregnancy generate deleterious effects on maternal and fetal health. Objective: to determine the influence of nutritional status at the 3rd. trimester on birth weight in pregnant in Bayamo. Methods: a longitudinal observational study was conducted in a sample of 53 pregnant women from the health areas of Bayamo municipality, Granma, from December 2011 to April 2012. The influence of anthropometric indicators such as body mass index at enrollment, weight changes made in the 3rd. quarter as well as energy and nutrient intake, biochemical indicators of nutritional and metabolic-birth weight were studied. Results: the parameters of body mass index at enrollment and weight changes were significantly associated with birth weight groups. Nutritional indicators, body mass index at enrollment and consumption of vitamin E significantly positively correlated with birth weight, whereas iron intake significantly did inversely. Conclusions: the results confirm that the parameters of anthropometric indicators of nutritional status of pregnant women are associated with birth weight, but not the consumption of energy, protein and some micronutrients in pregnant women in this study, as well as biochemical indicators nutritional and metabolic studied.

Keywords : pregnant; nutritional status; body mass index; weight changes; nutrient intake; weight at birth.
